Getting data plan for T-mobile to work?

[Peaceful]

I have an unlimited data plan with T-mobile (US). The data plan works fine with a T-mobile phone. I just got a 1st gen iPhone and went through the unlocking process, and everything works great with the exception of data over the cellular network. What am I missing?

Never mind. I found the answer on:

"- To enable EDGE go to Settings - General - Network - EDGE. APN will be wap.voicestream.com, username and password will be guest.

Actually set the APN to epc.t-mobile.com. I've done that, and it works great. You can even check your minutes and stuff by going to wap.t-zones.com in the iphone browser.
